- BACKGROUND: To study the acute effect of nateglinide, an insulinotropic agent, on the postprandial triglyceride and lipoprotein responses in subjects at risk for type 2 diabetes. METHODS: Six women and 10 men, with at least one first-degree relative with type 2 diabetes were included (Age: 48 +/- 7 years, BMI: 27.5 +/- 2.8 kg m(-2), P-triglycerides: 1.3 +/- 0.4 mmol L(-1), P-cholesterol: 5.4 +/- 0.6 mmol L(-1), B-glucose: 4.6 +/- 0.3 mmol L(-1)). They each had two 8-h meal tolerance tests with either nateglinide or placebo given 10 min prior to the meals in randomized order. Lipoprotein fractions were separated by density gradient ultracentrifugation. First-phase insulin secretion was assessed by an intravenous glucose tolerance test (300 mg kg(-1) body weight) and insulin sensitivity by a hyperinsulinaemic euglycaemic clamp (40 mU m(-2) min(-1)). RESULTS: The 1-h insulin levels during the meal tolerance test were significantly higher with nateglinide (577 +/- 81 vs 376 +/- 58 pmol L(-1), p < 0.001), as well as the response during the first two hours (IAUC: 41 243 +/- 5844 vs 29 956 +/- 4662 pmol L(-1) min, p < 0.01). Accordingly, nateglinide lowered the 8-h postprandial glucose response by around 60% compared to placebo (p < 0.001). In contrast, no significant lowering was seen in the excursion of postprandial triglycerides in total plasma or lipoprotein fractions. Consistently, the concentration of exogenous (apoB-48) and endogenous (apoB-100) lipoproteins was not reduced by nateglinide. CONCLUSIONS: Acute administration of nateglinide reduces, as expected, the postprandial glucose concentration, but no reduction in triglyceride or lipoprotein responses are seen in subjects at risk for type 2 diabetes.
